The Discussion Board can be used for many purposes. It is an important tool for interpersonal interaction, and can help build a sense of community among students.
A Blog is your personal online journal. Each blog entry you make can include any combination of text, images, links, multimedia, Mashups, and attachments. Blogs are an effective means of sharing knowledge and materials created and collected by the group in the course. You can post entries and add comments to existing blogs.
Wikis are collaborative collections of information that use interlinked pages to present and organize the data. With this tool, multiple students can share and collaborate on one or more pages of content. Wikis can be easily updated, expanded, and edited, and can also be used to record information and serve as a repository for course information and knowledge.
The Chat tool allows you to interact with other users using a text-based chat. This tool can be used when real-time discussion is required.
